Fish Habitat & River Restoration

Climate change is the most consequential challenge facing our planet and is impacting our rivers and water supplies first and hardest. Communities are struggling to do more with less water, fish and wildlife are fighting to survive, and storms are triggering more life-threatening floods. Our clean water and rivers will suffer permanently if we don’t take immediate action.

Our air, water and homes are threatened

For millennia, we have depended on a stable climate which has shaped every part of our way of life. Now, we face the frightening reality that this foundation will crumble within our lifetimes unless we take immediate and decisive action to transform our energy system. Communities across America are already feeling severe impacts, with working-class people and people of color being hit hardest. Visit the Sunrise Movement to find out what you can do!

Bandon Community Radio’s Executive Director, Kelly Miles, is a former Port of Bandon Commissioner and spent nearly 8 years as the Director of the Coquille Watershed Association in Coquille, Oregon. She is passionate about marine and river ecology, and was fortunate to work with many fine landowners and biologists on dozens of salmon habitat restoration and water quality projects.

While with the Watershed Association, Kelly was honored to work with renowned fish passage engineer, Răzvan Voicu, PhD, on river restoration papers published in the Transylvanian Review of Systematical and Ecological Research in Sibiu, Romania. You can view some of Dr. Voicu’s papers below:

Currently, in Romania, the restoration of the longitudinal connectivity of the rivers is still in its beginning stages and many of the spillways and dams need migration systems. Dr. Răzvan Voicu, among one of the few specialists in this field, has designed various fish crossing systems over transverse hydrotechnical constructions. Some of them have been published with various foreign experts (US, Australia, Canada, Poland) certifying the correctness and engineering effectiveness of these proposed systems. The only (partial) design that has been put into working practice as of yet is at the Mănăstirea Dam in Cluj County (see pictures below taken by Melinda Haragus Sipos).

Well done, Dr. Voicu! The fish thank you!
